Original application filed July 23, 1913, Serial No. 780,673. Dividedand this application led July 16, 1914. Serial No. 851,306.

To all whom t may concern:

Be it known that I, ORLAND L. IHRIG, a citizen of United States,residing at Sunnyvale, in the county of Santa Clara and State ofCalifornia, have invented a certain new and useful Improvement in FloatFeed Controls, of which the following is a specification.

My invention relates to improvements in float feed control means formaintaining constant the level of liquids in tanks and the like.

It embodies subject matter divided out of my co-pending application No.7 80,673, which was iiled July 23, 1913.

It is illustrated diagrammatically in the accompanying drawing, whereinis shown a horizontal section through my device.

Figure l is an axialrsection of the device. Fig. 2 an enlarged detail ofthe plug valve with the float member in raised position.

Like parts are indicated by the same letter in all figures.

A is a tank.

A1 is a valve housing contained in an aperture in the bottom of the tankand held firmly in position by a nut A2 which draws the shoulder A3 downagainst the bottom of the tank. A4 is a liquid supply pipe connectedwith said valve housing and A5 is a valve seat.

B is a valve stem having a plug valve B1 on the lower end thereof inopposition to the valve seat A5.

y B2 is a holding ring held on the valve stem by the pin B3 and B4t is avalve spring contained within the valve housing and surrounding thevalve stem resting upon the shoulder B5 at one end compressed by thevalve ring B2 at the other. The valve stem B projects upwardly from thevalve housing A1.

C is a float having the guide sleeve C1 centrally disposed thereinsurrounding and in slidable engagement with the valve housing C1. Thisfloat has a flat top C2 which rests on the upper end of the valve stemB.

C3 is a guard housing surrounding the ioat and valve housing fixed inposition by the braces C4 on the tank A and having avent C5 in the topthereof.

I claim:

A float feed valve comprising a vertical valve housing, having an opentop, a valve seat in the bottom thereof, a valve stem contained thereinand adapted to project thereabove, a valve carried thereby in oppositionto said seat, yielding means contained within the housing andsurrounding the stem for closing the valve, and a float surrounding andguided by the housing and adapted to rest directly upon the end of thevalve stem, the housing being closed against liquid discharge except atits open top, the iioat being adapted to completely cover and inclosethe housing but spaced therefrom to permit passage of liquid down alongthe outer wall of the housing between it and the float.

In testimony whereof, I ailiX my signature in the presence of tvvoWitnesses this 7 th day of Jui 1914.
